SUMMARY OF THE INVENTION The invention relates to an improvement in adevice for applying a liquid to a joint in a fluid line for thedetection of a leak therein when bubbles form in the liquid. Moreparticularly the invention includes a deformable bottle having a neck inwhich is mounted a stopper, the stopper having socket means in which oneend of a flexible tube is positioned. At the bottom of the socket isformed a flow hole which communicates with a second socket in which asecond tube is mounted. One of the tubes picks up fluid from within thebottle and the other tube allows application of a liquid to a line forthe detection of a leak therein by simply deforming the bottle. Thestopper also includes a storage socket for the outer free end of eachtube which also prevents flow of fluid from the bottle.

In the drawings forming part of this application:

FIG. 1 is a perspective view of a squeeze bottle with an applicator tubein position for detecting a leak in a pipe joint and embodying theinvention.

FIG. 2 is a perspective side elevational view of the bottle.

FIG. 3 is a sectional view of the line 3-3 of FIG. 2 with portionsbroken away.

FIG. 4 is a sectional view on the line 44 of FIG. 3.

Referring to the drawings in detail the device A includes the deformableplastic bottle which contains the testing liquid. The bottle A is formedwith the neck 12 open at the upper end. Further provided is thesubstantially cylindrical double ended stopper 14 which frictionallyfits in the neck 12. The stopper includes the hollow cylindrical portion16 and formed internally and centrally of the portion 16 is the wall 18.The wall 18 has formed axially thereof the flow hole 20. The numeral 22designates a first tubular socket for the end of a first flexible tube24 which is formed as part of the wall 18 and which extends axially fromthe flow hole 20. The end of tube 24 when in the socket 22 bottoms outon the wall 18 as a stop shoulder, for the flow hole is of less diameterthan the inside diameter of the socket 22. A second tubular socket 26for the end of a second flexible tube 28 is provided which is identicalto support 22 and which extends axially of the flow hole 20 oppositelydisposed to the tubular support 22. The end of tube 28 bottoms out onthe wall 18 as a stop shoulder when in the socket 26 as in the case ofsupport 22. The wall 18 acts as a shoulder for the end of each tube.

Further provided is a first storage socket 30 formed between the wall ofportion 16 and the support 22 which bottoms out on the central wall 18.Also provided is a second storage socket 32 formed between the wallportion 16 and the support 26 and which bottoms out on the central wall18. Each of the sockets 30 and 32 receive the outer free end of thetubes 24 and 28, respectively, for storage when not in use as shown inFIG. 2 in full lines and in broken lines in FIG. 3 with the tube 24. Thetube 28 may be similarly stored in socket 32. When the end of a tube ispositioned in a storage socket fluid is prevented from issuing out ofthe tube.

. The tubes 24 and 28 differ in that the tube 24 is relatively long andthe tube 28 relatively short, the tube 24 used in situations where asuspect leak area to be tested is difficult to reach. To use the tube 28instead of the tube 24 as in FIG. 3, the stopper 14 is removed from theneck 12 and reversed whereby the tube 24 is inside the bottle and thetube 28 outside thereof.

The device A is used by filling the bottle 10 with a liquid thatnormally is bubble free. The tube such as 24 is positioned in the socket22 and bottomed out on the wall 18 as in FIGS. 1 and 3 and the bottlesqueezed to cause liquid to be forced from the bottle and out throughthe tube 28, through the flow hole 20, out the tube 24 in an unbrokenstream. The liquid may be directed to a suspected leak at a joint suchas J as in FIG. I. If the liquid bubbles a leak is present. Similarlythe short tube 28 may be used by reversing the stopper l4. Either of thetubes used may be stored by forcing the outer end of the tube in itsrespective storage socket 30 or 32 as illustrated in FIG. 2.

What is claimed as new and desired to be secured by Letters Patent ofthe United States is:

l. A container with applicator tubes for dispensing a liquid, comprisingin combination:

a. a deformable bottle having,

b. a hollow neck,

c. a stopper having first and second identical ends,

each of said first and second ends being snuggly insertable into saidhollow neck,

d. said stopper having a first socket formed in said first end and e. asecond socket, identical to said first socket, formed in said second endof said stopper, said first and second sockets terminating in an,

I. inner wall having a,

g. flow hole axially of said first and second sockets and of a diameterless than the diameter of said first and second sockets,

h. a tube mounted in each of said first and second sockets incommunication with said flow hole and in contact with said inner wall,

i. said stopper including identical storage sockets formed in said firstand second ends for receiving the free end of said first and secondtubes to seal off the same.

2. The device as in claim 1 wherein one of said first and second tubesis of a greater length than the other. 4 I
